## Abstract Multiwall carbon nanotube (MWCNT) fibrils were introduced into TiO~2β__x__~N__~x~__ photoelectrodes to enhance charge collection efficiency as chargeβtransport pathways. For comparison, we also synthesized MWCNT/TiO~2~ nanocomposites to fabricate dyeβsensitized solar cells (DSCs). The e
Porous TiO 2 (anatase, rutile) belongs to the class of materials with very low drift mobility of electrons (10 Β± Β±4 Β±10 Β± Β±7 cm/Vs). The drift mobility is limited by traps being responsible for the slow interparticle charge transfer. The deep traps are generated at the TiO 2 surface in oxygen defici
